[0001] The present invention relates to a colander with reduced dimensions.
[0002] Colanders of different sizes and forms are found in the household goods sector, naturally
designed to separate the water used in a cooking pan from the pasta.
[0003] As known in the art, these objects are generally casings in the form of spherical
bowls with a series of small holes, in the concave part of which the foodstuff collects
while the water drains through these small holes.
[0004] Colanders, usually made of stainless steel or plastic, also have supporting means
such as feet, usually three, which allow them to be placed on a surface of a kitchen
sink for the draining operation.
[0005] Moreover, or alternatively, they may have other supporting means such as a handle
to support the colander over a sink while pouring the content of a cooking pan.
[0006] However, these colanders with their spherical form have considerable dimensions,
and therefore a certain amount of space is required to place them in a cupboard.
[0007] The general object of the present invention is to produce a colander with reduced
dimensions which allow it to be stored, when not in use, in a minimum space.
[0008] Another object is to solve the aforesaid drawbacks of prior art in an extremely simple,
inexpensive and particularly functional manner.
[0009] In view of the aforesaid objects, the purpose of the present invention is to produce
a colander with reduced dimensions, with the characteristics set forth in the attached
claims.
[0010] The structural and functional characteristics of the present invention and its advantages
in relation to prior art shall become clearer and more evident by examining the following
description, with reference to the attached drawings, which show a colander with reduced
dimensions produced according to the innovative principles of the invention.
[0011] In the drawings:
- Figure 1 shows an axonometric projection of a colander according to the invention,
in a draining position;
- Figure 2 is a median section in a side elevation of Figure 1;
- Figure 3 shows an axonometric projection of the colander in Figure 1, in a position
with reduced dimensions, where a first casing in the form of a spherical bowl can
be seen internally and a second casing in the form of a spherical segment with two
bases can be seen externally;
- Figure 4 is a median section in a side elevation of Figure 3;
- Figure 5 shows a top plan view of the first casing in the form of a spherical bowl
of Figure 3;
- Figure 6 is a side elevation view of Figure 5;
- Figure 7 shows a top plan view of the second casing in the form of a spherical bowl
of Figure 3;
- Figure 8 is a median section in a side elevation of Figure 7, taken according to the
trace line VIII-VIII of Figure 7.
[0012] With reference to the drawings, a colander with reduced dimensions according to the
present invention, is indicated as a whole with 10, and in the example shown according
to the present invention, has at least two casings 20 and 30.
[0013] Figures 5 and 6 show a first casing 20, which is in the form of a spherical bowl
and constitutes a lower part of the colander 10 in the draining position.
[0014] This casing 20 has a series of small through holes 22 designed for drainage.
[0015] The first casing 20 is also provided with feet 24 for resting on a surface on which
drainage can take place, for example the surface of a kitchen sink. The feet 24 are,
in the non-limiting example shown in the figures, three in number and are positioned
equidistantly from one another.
[0016] In figure 4 the feet 24 have a cylindrical surface portion, with an axis parallel
to the axis of the spherical bowl of the first casing 20 and which starts from an
upper circular rim 26 of said bowl.
[0017] Each foot 24 is provided with a tab 28 with an element 29 projecting laterally towards
the outside of the first casing 20.
[0018] Figures 7 and 8 show a second casing 30, which is in the form of spherical segment
with two bases and constitutes an upper part of the colander 10 in the draining position.
[0019] The spherical segment of the second casing 30 has an internal radius slightly larger
than the external radius of the spherical bowl of the first casing 20.
[0020] Moreover, the lower base of the spherical segment with two bases of the second casing
30 is smaller than the base of the spherical bowl of the first casing 20.
[0021] In correspondence with the feet 24 of the first casing 20, guides 34 are produced
on the second casing 30 for said feet 24. In the non-limiting example shown in the
figures, the guides 34 are three in number and are positioned equidistantly from one
another.
[0022] In Figure 4 the guides 34 comprise a portion of cylindrical surface, the axis of
which is parallel to the axis of the spherical segment of the second casing 30 and
which has a slightly larger internal radius than the external radius of the cylindrical
portion of the feet 24.
[0023] Operation of the colander with reduced dimensions according to the invention is clear
from the preceding description with reference to the figures, and is described briefly
below.
[0024] The second casing 30 is fitted around the first casing 20, so that the respective
axes, of the spherical segment with two bases and of the spherical bowl, coincide
with each other.
[0025] More precisely, the feet 24 of the first casing 20 are positioned in correspondence
with the guides 34 of the second casing 30 and are thus inserted in said guides 34.
[0026] At this point the colander 10 is assembled, the second casing 30 being able to slide
axially on the first casing 20.
[0027] In practice, two relative positions between first 20 and second 30 casing are relevant:
a draining position, shown in Figure 1, and a position with reduced dimensions, shown
in Figure 3.
[0028] In the draining position shown in Figures 1 and 2, bearing in mind what has been
said concerning the dimensions of the internal radius and of the lower base of the
spherical segment with two bases of the second casing 30, it must be noted how a lower
part of the second casing 30 covers an upper part of the first casing 20 in a relatively
accurate manner, preventing substantial leakage of water.
[0029] If pressed, the tabs 28 of the feet 24 can bend so as to bring the projecting elements
29 towards the inside of the bowl of the first casing 20, returning to an initial
position at rest in the absence of external forces.
[0030] In practice, as shown in Figure 2, when the colander 10 is in the draining position
the projecting elements 29 of the tabs 28 engage at a lower end of the guides 34 to
prevent the second casing 30 from sliding downward, thus producing removable fixing
means between first 20 and second casing 30 and thus allowing the colander 10 to be
used for drainage.
[0031] By instead exerting a certain pressure downward on the second casing 30, and if necessary
also pressing the tabs 28 towards the inside of the first casing 20, the projecting
elements 29 are disengaged from the second casing 30, allowing it to slide downwards
to the position shown in figure 4.
[0032] The colander 10 of the present invention in another embodiment not shown in the figures
may have no feet 24 and be provided with an elongated maneuvering handle, being provided
in any case with removable fixing means between a first casing 20, in the form of
a spherical bowl, and a second casing 30, in the form of a spherical segment with
two bases.
[0033] It is thus emphasized how, with the colander 10 of the present invention, it is possible
to obtain a reduction in the height occupied by a prior art colander, with the analogous
dimensions in the draining phase. In the non-limiting example shown in figure 4, this
reduction is of around half.
[0034] To attain greater reductions, it will be necessary to divide the second casing 30,
in the form of a spherical segment with two bases, for example into two parts, connected
in an analogous way as described with reference to the connection between the first
20 and the second casing 30 shown in the figures.
[0035] Furthermore, it is emphasized that the axis of the cylinders of the feet 24 and of
the guides 34 may also not be parallel to the axis of the casings 20 and 30, as long
as they have axes substantially parallel to one another.
[0036] It is specified that the colander 10 of the present invention is advantageously produced
in plastic material.
[0037] From the preceding description with reference to the figures, it is evident how a
colander with reduced dimensions according to the invention is particularly useful
and advantageous. The objects mentioned in the preamble of the description are thus
attained.
[0038] Naturally, the forms of the colander with reduced dimensions may vary from those
shown purely as a non-limiting example in the drawings, as may the materials and removable
fixing systems differ.
